Chapter 8 Chapter Seven The Third Person

"Ding Ling Ding Ling..." The sudden ringing of the phone in the middle of the night, to the forensic doctor, often means that someone has died unexpectedly.Since I started working in the provincial department, the probability of me receiving such a midnight ringtone has been much lower, so when the ringtone rang loudly that night, I almost broke out in a cold sweat. Press the answer button. "Is Li Dabao with you?" a female voice asked quietly. I breathed a sigh of relief, picked up the alarm clock on the bedside table and took a look.After eleven o'clock in the evening, it's okay.This is Li Dabao's girlfriend Cha Gang.In the evening, Dabao and I participated in a full moon banquet for a colleague's child, and Dabao accidentally drank too much.

"We finish at ten o'clock." I didn't betray Dabao, in fact we finished at eight o'clock. While talking, there was a knock on the door from the microphone, and Dabao's girlfriend said, "I'm back." Then she hung up the phone. Early the next morning, I said to Dabao, who had swollen eyes, "I fooled around outside for more than three hours last night. What did you do?" "Alas! Not to mention, thanks to the evidence of mechanical damage, otherwise I would really not be able to explain it clearly." Dabao said as he rolled up his sleeves and trouser legs, revealing the scratch marks on the joints.

"According to my experience, this is a bruise, which is formed by the ground, and it is formed by multiple bruises in different directions. It is indeed not a scratch of a woman's nail." I joked. "I drank too much yesterday, and I just remember riding my bicycle home, and I don't know anything else." Dabao took a sip of the yogurt in his hand and said, "I heard from my girlfriend this morning that I got home after eleven o'clock. Yes, I was wondering, usually I can ride home in half an hour, why did I ride for more than three hours? And why do I have so many injuries? After much deliberation, the only possibility is that there is something wrong with the bicycle. So I just went to the scene to investigate once, and guess what?"

I shook my head. Dabao said: "My bicycle, the chain is gone." I was stunned for a moment, and then I laughed and laughed: "You mean, you just kept riding up, falling down, riding up, falling down like this? You fell home for three hours?" Dabao pushed his glasses on the bridge of his nose, nodded, with an embarrassed look on his face. "You are so talented." I laughed and said, "When your girlfriend called me, I was still afraid that you might be fooling around. If that's the case, I must expose you, and you will be notorious. " "How can it be so easy to be notorious?" Dabao said, "Unless when you show up at the scene, you find that I died naked on someone else's bed."

"Ding Ling Ding Ling..." "Stinky mouth." Seeing that it was the master's office caller, I frowned and said, "If there is a case, the person who died must be the person who died naked on the bed." "Let's go to Chengcheng City right away. A case of two deaths has just been reported." The master said, "Call Shang Dabao and Lin Tao to go together. If the case goes well, I will go to Longdu County to perform the duty of homicide supervisor. Longdu has been there for half a year. The previous murder case has not been solved." "What is Cheng Cheng's case?"

"An old man and an old lady died naked on the bedside." Master said. Chengcheng City is a small city located to the west of Yuntai City. Its economic situation is far worse than Yuntai City, and its population is very small. Therefore, Chengcheng City's annual crimes are the lowest in the whole province.This time, two people died all at once, and the leaders of the city bureau were a little panicked, and immediately notified the provincial department. Although there are very few opportunities to go to Chengcheng, I still pay more attention to Chengcheng.Because Longdu County under the jurisdiction of Chengcheng City is the place where one of the "Yuntai Cases" took place.

The site is located in a densely populated area of ​​one-story houses in Chengcheng Development Zone.This area is like a ghetto in a movie, dilapidated and devastated. "What kind of place is this?" I took out gloves from the investigation box and put them on, and asked the head of the criminal police detachment beside me, Cao. "This area was originally cultivated land," said Captain Cao. "Recently, I heard that the large-scale construction of the development zone is coming here, so the houses you see are basically built overnight. There is only one, waiting for demolition."

I was surprised to see some of the two-story buildings that were built in a very high-grade way, and sighed: "Human beings are so great!" Forensic doctor Xiao Yang from Chengcheng City came over and shook my hand.Chengcheng City has a population of 400,000, but there are only three forensic doctors. One of them participated in the job competition and jumped to work as an instructor in the Criminal Investigation Brigade.The remaining two forensic doctors are all students I taught in the professional technical training class the year before. It is not easy to shoulder such a heavy workload after only two years of work.

"Since the houses are self-built and the purpose is to wait for demolition, does that mean that there are no people in these houses?" I asked. Captain Cao shook his head and said: "No, according to the preliminary investigation, there are seven or eight households who live here for a long time, more than ten households live here occasionally, and the remaining dozens of houses are empty. " "Won't such dense construction cause disputes over uneven distribution of land?" I am full of curiosity about such things. "It used to be a public land. During the two days when the house was built, we did not receive a dispute report. The people are very united."

"What's the result of your initial survey?" I turned to ask Xiao Yang.Xiao Yang is my student. Although he is no more than two years younger than me, I unconsciously call myself a teacher. "The male deceased is named Fu Li, and the female is named Zhang Huarao. At present, the male deceased should have suffered more serious injuries. Zhang Huarao seems to have no damage, but we have not turned over the body, and we are waiting for you to come." This may be the first double murder case that Xiao Yang encountered after working, so he seemed a little panicked. I habitually walked around the site. This is a self-built red brick bungalow with only one room and no partitions.On the north side of the house, there is a red lacquered double door, and there is a window next to it with closed curtains.The window sill is a bit high, and a person who is 1.7 meters tall can barely see the indoor situation standing in front of the window.Below the window was a flower bed, which had been cordoned off.

The south side of the site is a wall with no windows and only a single small back door.It seems that the whole house is very uncoordinated, which shows that this should be a hastily built unfinished house. Lin Tao was squatting at the back door, carefully brushing the side of the door with a small brush. "How, did you find anything?" According to my intuition, this case should not be difficult. Lin Tao shook his head: "The back door was pried open. The door lock is of poor quality. If you pry lightly, it will be useless. According to the direction of the footprints, this door is an entrance and exit. But the wooden door is too rough to extract fingerprints. .” "Where are the footprints? Can't you tell the direction? Is there a comparison condition?" I asked. Lin Tao stopped what he was doing, wiped the sweat off his forehead with his elbow, pointed to the room, and said, "On the red brick floor, you can only see the outline, but no pattern, and there is no comparison condition." With a disappointed expression on my face, I put on my shoe covers, opened the door and entered the house. As soon as I entered the room, a warm wind full of bloody smell hit my face. It was a very strong bloody smell. I couldn't help but raised the back of my hand and rubbed my nose. It was already autumn, and the power of the autumn tiger had been greatly reduced.But because the house is airtight, the indoor temperature is still five degrees Celsius higher than the outdoor temperature.The house was messy, with a bed, a dining table, a pot and a stove, and a "bathroom" separated by a curtain in the corner.The people who live here seem to be eating, drinking, and sleeping together. The light in the room was on, a dim incandescent bulb.Because the voltage is unstable, the lights are still flickering. "When you came, the light was on?" I turned off the light, and although there was still plenty of light outside, the scene suddenly became dark.I was afraid of affecting the trace inspection work, so I quickly turned on the light again. "It was the neighbor next door to the deceased who reported the crime." Captain Cao said, "Around four o'clock in the morning, the neighbor came over because of an emergency, and found that the lights of the deceased's house were still on. He pushed the door and found that the door was closed, so he walked around. Go to the back door. The back door was ajar, so the neighbor bravely opened the door and found blood on the wall beside the bed." "Who is the owner? Scruffy?" I asked. "I just made a clear investigation. The owner of the house is an old lady. The house is sloppy, but the people are very particular." Captain Cao said, "I treat myself like a girl every day, and I dress up beautifully, and there are countless jingles." "Dingdangzi" is a local slang term for concubines. I nodded, as if I had some confidence in my heart.In fact, the more complicated the social relationship is, the easier it is to find contradictions in the investigation, and the easier it is to bring clues to the case. As Master said, the two deceased were naked, lying side by side on a small bed with their legs drooping by the side of the bed.An old-fashioned electric fan was placed beside the bed, and it was still shaking its head feebly.It seems that the warm wind with the smell of blood rushing towards the face just after entering the door came from this. The male deceased had wrinkled faces and looked to be in his sixties. His hair was already soaked in blood, but no obvious damage was seen.The overflowing feces could be seen between the deceased's legs, emitting a foul smell. Urine also dripped down his thighs to the ground. "It looks like a severe head injury." I rubbed my nose and said, "I'm incontinent. Besides, isn't this woman that old? Can't she be called an old lady?" Captain Cao looked down at his notebook and said, "Well, she's not very old, she's forty-two years old. How did you know that? I think she's fifty years old." I smiled and said, "I used to talk to a teacher who was known as a nipple expert (see the case of 'Floating Wreck' in the first part of the 'Forensic Qin Ming' series)." Looking at Captain Cao's puzzled eyes, I didn't explain too much. I took out the corpse thermometer from the investigation box and inserted it into the anus of the dead man, which was covered with feces. "It's nine o'clock in the morning, and the temperature of the corpse has dropped by 10.5 degrees Celsius. Well, the temperature of the two corpses (see the case of 'Floating Wreck' in the first part of the 'Forensic Qin Ming' series) is about the same." I analyzed, " According to the law that the normal room temperature drops by one degree Celsius every hour for the first ten hours, and then drops by 0.5 degrees Celsius every hour thereafter, the deceased should have been dead for eleven hours, that is to say, he was killed around ten o’clock last night.” Captain Cao nodded.He has worked as a criminal policeman all his life, and he is still very familiar with this method of calculating the time of death. "Let's not look at the injuries of the deceased for now, let's drag the body to the funeral home first." I said, "I'll look at the scene again." After the body was dragged away, I looked at the bed and walls around the deceased, and there were no other valuable clues except for a lot of splattered blood and some white brains.So I started pacing the scene again, hoping to make further discoveries. Not only is the site small, but it's also messy.All kinds of girly clothes and brightly colored underwear are thrown everywhere. It seems that this forty-two-year-old woman really likes to think of herself as a young girl. "There was a thick layer of dust on the furniture at the scene. Isn't this house where Zhang Huarao usually lives?" I asked. "Well, in layman's terms, this house was used by Zhang Huarao as a fort." Captain Cao said, "Zhang Huarao has a husband who works away for a long time. We also contacted him. He is still out of town. I heard that his wife He died, but there was no reaction, saying that the public security organs should handle the body.” "Fortress... um, it's a place to fuck? Besides, her husband doesn't want to come back to see her for the last time," I said. "Isn't it abnormal to be so indifferent?" "It's not unusual," Captain Cao said, "Anyone with a wife like this will be indifferent. We've investigated, and her husband is fine. He was indeed out of town last night." I lowered my head and thought for a while, and suddenly saw a pile of daily tools in the corner of the back door, and I became interested immediately.I walked to the pile of tools, squatted down and looked at it carefully for two minutes, and said, "It seems that passion kills people." "How do you know that?" Detachment Captain Cao squatted next to me and asked. "Look," I said, "this pile of tools hasn't been moved for a long time, and they're all covered with a thin layer of dust." Captain Cao nodded, picked up the camera in his hand and took pictures of the pile of tools. "But in the corner of this pile of tools, there is a fresh mark." I circled a shape with my finger, and continued, "Usually, such a piece of dust-free space will only appear after the items covered here are taken away." place." "Why can't I see it? Your eyes are so sharp?" Dabao squeezed over to look. "When you get closer, you can't see it." I said while taking out a bright flashlight and shooting a beam of side light, "Under this kind of light, it is clearly visible." Under the illumination of the flashlight, the shape of a hammer clearly appeared in front of us. "Tit hammer!" Dabao said. I nodded: "The brain tissue of the deceased showed signs of splatter, and there was a lot of bleeding. In such a scene, it is basically certain that the murder weapon was a blunt metal weapon without looking at the damage." "Understood." Captain Cao said, "Because the murderer pried open the back door, found the murder weapon directly near the back door, and killed people with local materials. This is very likely to be a murder of passion." "This is the current guess." I said, "but you can't rely on guesswork to handle the case. Let's examine the corpse first, and then make a comprehensive analysis based on the clues obtained from the trace inspection. Overall, this case is not difficult." In order to cope with the tasks of the provincial department, the Chengcheng Public Security Bureau is preparing to build a simple forensic autopsy room in the funeral parlor.Seeing that the leaders of the Chengcheng Public Security Bureau paid so little attention to forensic work, I couldn't complain, and I wanted to make a note of this in the year-end performance appraisal later. The autopsy was carried out in the open air on a vacant lot in the funeral home compound. Da Bao and Xiao Yang were examining Fu Li's body in the order of autopsy, but unfortunately they didn't find anything. "What is certain is that the deceased did not have restraint injuries." Dabao carefully cut open the skin of both wrists and elbows of the deceased to check whether there was hidden bleeding under the skin. "Passionate killings are usually sudden attacks, so there are very few restraint injuries." I slowly scraped the scalp of the deceased with a scalpel.Fu Li's black and white hair gradually piled up on my incision, revealing patches of grayish-white scalp. For forensic examination of a corpse, especially one with possible head injuries, the hair of the deceased must first be shaved.There are many cases where forensic doctors are lazy and unwilling to shave their hair. As a result, important injuries have not been discovered, and important clues have been cut off.Therefore, a good forensic doctor must be a good barber.Raising the knife with the hand and dropping it, the skin is removed without hurting the hair. The most difficult part of shaving is the hair near the wound. Because the skin is broken, there is no tension, and it is difficult to shave the hair at the wound.In order to maintain the original condition of Fuli's head injury, I carefully shaved off the stubble around his occipital wound.I didn't finish my work until Dabao and the others dissected the neck, chest and abdomen of the deceased. "I'm really old, and my waist is really bad. Back then, I stood on the dissection table for nine hours, and it was completely fine." I slowly straightened my already stiff waist, and said. "No damage was found on the deceased's whole body." Dabao obviously didn't hear my complaint because of his high concentration. "There is injury in the occipital area." I posted a scale around Fuli's occipital wound, and said while taking pictures, "There are four or five dense wounds in the occipital area. There are obvious contusion bands on the edge of the wound, and interstitial bridges can be seen in the wound." , brain tissue spillover." I cut open the dead man's scalp, and continued: "The occipital skull has a depressed fracture, and the fracture line is cut off. From this point of view, the deceased was hit by others with a metal blunt instrument on the occipital many times, resulting in extremely severe head injury and died instantly. Yes. Because there is a contusion zone around the wound, it shows that the contact surface of this blunt metal instrument is very rough." "Well, that, the teat hammer can completely cause such damage." Dabao said. "Hurry up and sew." Xiao Yang said from the side, "This man is incontinent, and the smell is terrible." "Can it be more stinky than the view of giants?" Dabao said, "To be a forensic doctor, you must be able to stand the stink." "Yeah." I stared at Fu Li's forehead and said, "If the autopsy was not meticulous because of the smell, then it was all white smoked by the smell before. Look, there is a damage on his forehead. No abrasions, with minor subcutaneous bleeding, which was the result of a collision with an object that was soft on the outside but hard on the inside." "Hey, I really didn't notice this injury." Dabao said, "The process of the murderer hitting the forehead of the deceased with his fist?" "It's hard to say," I said, "but it shouldn't be of much significance. We've determined that the murderer broke into the house, obtained local materials, murdered passionately, and attacked suddenly. The scope of investigation should not be large." When Zhang Huarao's body was carried onto the corpse bed, even though the deceased was said to be the largest, I still felt sick.The woman's face was covered with a thick layer of powder, her staring eyes were painted with black eyeliner, and her hair was dyed auburn and tied behind her head. "Is she a chicken?" I couldn't help asking. The investigator who was in charge of the camera shook his head and said, "No. According to the investigation, this woman does not prostitute, but seeks all kinds of lovers. She belongs to the kind with extremely strong sexual desire. She can date several jingle girls in one night. " "There is a lot of semen in the vagina, extract and test." Dabao said, "This old man can still have so much semen." "That's not normal," Xiao Yang said, "The older you are, the more you have." "Hehe, you are quite experienced." Dabao laughed. I glared at them both and stopped their teasing.My job is still to shave my head. Since there were no open wounds on the woman's head, the work of shaving the hair went very quickly this time. When Dabao opened Zhang Huarao's chest and abdomen, I had already finished shaving. "You can feel bone abrasions. There are two flaky abrasions on the temporal part of the deceased." I cut open the scalp of the deceased while talking, "Sure enough, the corresponding parts of the abrasions were bleeding under the skin, and the skull was depressed." "We didn't find any injuries here. The injuries of this woman and the old man are very similar." Dabao said, "There are no other injuries on the whole body, and the only injury is on the head." "Besides, the diameters of the injuries on both heads are about three centimeters, which should be caused by the same tool." I said, "The head injuries of the male deceased were heavier, while those of the female deceased were less severe, but both were fatal. damage." I don't like craniotomies. The smell of the bone fragments raised by the craniotomy saw after being burned by the saw blade at high temperature is the smell I am most afraid of smelling in my life. However, the forensic doctor had to open the skull.Even if the cause of death can be determined, it must be prescribed. Zhang Huarao's scalp is thicker than the average person's, but the skull is thinner than the average person's, so the same strength and the same tool can cause different injuries on Fu Li's and Zhang Huarao's heads.But when the skull was opened, the two were highly unified, and the brain tissue was accompanied by local contusion and extensive bleeding, which was fatal. "Look," I said, pointing to Zhang Huarao's forehead, "it's very strange, even a piece of subcutaneous bleeding on the forehead is the same as the old man's. The murderer's modus operandi is quite fixed." In this case, like many cases, the investigators know what to do next without the guidance of forensic medicine. At the special case meeting, I said: "According to the results of the on-site investigation and autopsy of this case, we believe that the deceased was killed around ten o'clock last night. We believe the two deceased were killed by the same individual." "The murderer you speculated before was a passionate murderer. Is there any evidence to support it?" Cao Detachment Captain said. "Yes," I said, "an imprint was found at the scene. It can be concluded that the murderer directly obtained tools from local materials after prying open the back door. Such a situation is usually seen in murders of passion." I picked up the mineral water bottle on the table, took a sip, and then said: "The head injuries of the two deceased are very simple. Speaking of characteristics, one is heavy, and the other is dense. It shows that the murderer did it in a short period of time. Strike the occipital of the male deceased and the temporal of the female deceased, resulting in the instant death of the two deceased. Since the action is simple and the purpose is clear, it should be a murder of passion or revenge. Combined with the problem of the imprint on the scene we mentioned earlier, passion should be considered kill." "What's the purpose of killing people with passion?" Cao detachment leader asked. In fact, I know Captain Cao has already figured it out, and I just want to further confirm what he thinks through forensic technology. I said: "The two deceased at the scene were both naked, and there were semen spots in the vagina of the female deceased. Combined with the investigation, the female deceased had promiscuity. Therefore, I think that the murder of passion in this case should be a kind of murder of love. In other words, It may be that Zhang Huarao made an appointment with two lovers this night, but the time was not calculated properly, and the lover who made an appointment at the back heard the movement outside the house, and became jealous for a moment, and then killed him." "It sounds reasonable." Captain Cao said, "It's basically the same as what I thought. The preliminary investigation found that Zhang Huarao did have a precedent for inviting several lovers to his house one night." "Is the investigation fully underway?" I asked. "We're sorting it out now." Captain Cao said, "I ask them to search carefully and not let any one go. After finding out all the men who had an affair with Zhang Huarao, they will be questioned one by one." "Unfortunately, we did not find valuable traces and physical evidence at the scene." Lin Tao said. "It doesn't matter, the murder weapon was taken away by the murderer, maybe something will be found on the murder weapon." Captain Cao said, "At present, the main starting point is to investigate people. I believe that the case can be solved within two days." "That's good." I said with a smile, "It's my girlfriend's birthday in a few days, and I have to go back before that day." Early the next morning, Dabao and I came to the interrogation monitoring room to watch the men being questioned. I sat in the monitoring room for more than two hours and questioned three men.These three men are either old or disabled, and there is also a homeless man. It can be seen that this Zhang Huarao is really hungry and hungry.However, after a simple review, all three men were decisively ruled out, because all three men had clear alibi. I turned around and asked the investigator who was sitting behind me: "How many people have you found had an affair with Zhang Huarao?" The investigator used a pen to click back and forth in the notebook, and said: "At present, there are forty-seven people who have been confirmed to have had sexual relations with the female deceased." "Forty-seven!" I was taken aback. "You can ask five at most in one morning. When are you going to ask?" The host investigator shrugged and expressed helplessness: "In addition to our two groups of people who are in charge of interrogating one by one, there are four groups of people who are in charge of peripheral investigations. In fact, interrogation is not the main task. Peripheral investigations may find more clues, and We have to verify the alibi provided by these people one by one." I stood up and patted my butt, and said, "That's a hard work for you, anyway, I don't know how to investigate, why don't I go to Longdu to see a murder case they haven't solved before." "Are you still going to Longdu?" "Yes," I imitated the lead investigator and shrugged my shoulders, "The task assigned by the leader, I have to go to Longdu to perform the duty of homicide supervisor in my free time when handling this case. Come on, I believe that when I come back, the case has been completed. broken." "Almost." The host investigator was full of confidence. Chengcheng City and Longdu County are only 30 kilometers away. We arrived at the Longdu County Public Security Bureau before lunch. After a brief lunch, we asked the county bureau to provide the files of an unsolved murder case half a year ago. "We have made twelve homicide cases this year, but this one has not been solved." The deputy director of the county bureau in charge of criminal investigation said, "But we are very confident in solving this case, but it will take a little time." As soon as the words fell, The female police officer in the archives room sent the file of the case. "That's good. I'm relieved to hear that the director is so confident." I flipped through the case file while perfunctory the director. After reading the on-site information of the case and the preliminary investigation situation at a glance, my expression gradually became dignified.Unable to believe my eyes, I opened the archive of photos from the scene again. Dabao noticed the change in my expression: "Well, what's the problem?" I didn't answer Dabao's question, and turned directly to the photo of the autopsy. After just one glance, I couldn't suppress the trembling in my heart, and I raised my head and asked, "Director, are you sure you didn't take the wrong file?" "Take... the wrong file?" The director was baffled by my question, "How could it be possible to get the wrong file? Ji Huanian's murder case, that's right, this is the file." "But," I said staring at the photo of the corpse in the file, "this is clearly the 'Yuntai Case'!" "'Yuntai case'?" The director said with relief, "Oh, Ji Huanian's case should have nothing to do with the 'Yuntai case'." "Seven years ago and five years ago in Yuntai respectively, the 'Yuntai cases' were reported in Yunxian and Longdu three years ago, all when the female students living in the school went to the toilet at night, He was taken hostage to a remote area near the toilet, his head was pressed, his mouth and nose were compressed, he died of mechanical suffocation, and then he raped the corpse." Speaking of the "Yuntai case", I felt a faint feeling of distress, "Although this case She is a female worker, but she is also on duty in the middle of the night to go to the toilet, and rapes the corpse after being suffocated near the toilet, the method of committing the crime is exactly the same, why is it different from the 'Yuntai case'?" "Section Chief Qin is very familiar with the 'Yuntai case'. However, I wonder if Section Chief Qin knows the basis of the 'Yuntai case'?" The director asked me back. "The reason why I pay attention to this case is that the first deceased in the case seven years ago was my girlfriend's cousin." I explained sadly, and then answered his question, "The basis for the above four cases to be linked, In addition to the modus operandi I mentioned, there is another characteristic, that is, a small amount of sperm spots were found in the bodies of the four deceased, but there was no sperm, so DNA typing could not be made." "Yes." The director said, "but in this case, a sperm spot with sperm was found in the body of the deceased, and the DNA genotype was also made. The relatives of Section Chief Qin were involved in this case, so I can understand my feelings, but we can't be like a friend. There are clear differences between the cases." "It turns out that the director's confidence in solving the case comes from the semen spots in the body of the deceased. With DNA, you are not afraid that you will not be able to solve the case, are you?" I said, "Do you have a computer in this conference room that can connect to the internal network of the police? " The chief pushed his laptop to me.I opened the parallel case system, downloaded the photos of several victims of the "Yuntai case" at the scene, and arranged them side by side on the computer desktop. "To tell you the truth, I recently discovered a new basis for the merger case." I said, "Look, the hands of the four deceased were tied behind their backs, right?" The chief nodded blankly. I went on to say: "You must not have noticed that the knots used to bind the hands of the four deceased are tied in the same way, and it is not a commonly used knot. It is a cumbersome but not practical knot." The director pushed his glasses up to his forehead, and squinted to observe several photos on the computer screen. Gradually, his expression became serious: "It's actually the same as the knot in our case." "You can also see it?" I said proudly, "So, I think this case and the 'Yuntai case' can be linked together. Because the murderer's semen and DNA typing were found in this case, so I think, The cracking of the 'Yuntai Case' is very likely to use this case as a breakthrough." "Then... what should we do next?" the director asked. "The next step is to step up the search for the owner of the semen, find the murderer as soon as possible, and prevent him from committing crimes and killing others." I said. The chief nodded. Dabao interjected from the side: "But, why there was no sperm in the first four cases, but there is sperm in this one?" I said, "I don't know about this issue either. No matter what, I'll make a report when I get back and apply for this case to be investigated together with the 'Yuntai case'." At this moment, my heart was full of excitement. The detection of the "Yuntai case" may really have dawned!After a sleepless night, I received a call from Lin Tao early the next morning. Lin Tao told us to return to Chengcheng City immediately, and the detection of the naked death case fell into a stalemate again. When rushing back to Chengcheng, Lin Tao was holding a pitch-black iron rod, looking left and right. "Where did you get the dog-beating stick?" I asked. Lin Tao didn't even raise his head: "This is the latch of the gate at the scene." "Crap, the door is obviously red." "A little bit of common sense, okay?" Lin Tao rolled his eyes at me, "We have fumigated this door latch for fingerprints, so of course it was fumigated black." I took a closer look and found that the red paint was indeed hidden under the black. I rubbed my head, a little embarrassed: "What? Didn't you say that the entrance and exit are the back door? Why did you start thinking about the door again?" "It was an unexpected discovery," Lin Tao said. "Yesterday afternoon, we re-examined the scene, but still did not find any valuable evidence. I also noticed the latch by accident, and found a fresh blood fingerprint on it." "Blood prints?" I said. "That must be relevant to this case." "Yes, it has been ruled out that this fingerprint belongs to the deceased. It is preliminarily judged that this fingerprint was left by the murderer." Lin Tao said, "Just now I smoked the door latch again, and found no other fresh fingerprints." "You are awesome." I patted Lin Tao on the shoulder happily, "With this fingerprint, it is not a problem to identify criminals. However, there is one question that I can't understand. Why did the murderer touch the latch of the gate? Since he It was by prying open the back door to enter the room, which means that the door should have been locked at that time." "The key problem is not here." Lin Tao said, "With this blood fingerprint, the special case team began to collect the network, and extracted all the fingerprints of the men who were found to have had an affair with Zhang Huarao at one time. I worked overtime last night. Made a comparison and ruled out all of them.” "Exclude all of them?" This result greatly exceeded my expectations. "Could it be that there were some omissions due to incomplete investigations in the early stage?" Lin Tao shook his head: "The task force said it was impossible, and the preliminary investigation is very clear." I leaned against the edge of the table, lowered my head and thought for a while, and said, "Could it be that our detection range was drawn wrongly?" "It's possible." Lin Tao said, "The case doesn't look as simple as we thought. I'm afraid you won't be able to make it to Sister Bell's birthday." "No." I forced a smile on my face, "I will find out what is wrong with the case today. Now I will go to the scene and have a look. Will you go?" "go." Although the body has been dragged away, the pool of blood, brains and feces left behind at the scene still exudes a disgusting smell in this airtight room.As soon as I entered the scene, I couldn't help rubbing my nose again. As soon as Lin Tao entered the scene, he turned on the multi-band light source that he carried with him, and irradiated the ground and walls everywhere. This is the case for on-site investigators. If the case is not solved, the investigation will not stop.That is to say, in this repeated investigation, more clues and evidence will be continuously discovered. The purpose of my visit this time is mainly to observe the shape of the bloodstains. I was deeply introspective. During the first on-site investigation and autopsy, I did not take into account the content of the reconstruction of the scene and the description of the criminals. I preconceived that the contradictions in this case were obvious, and the case should be solved quickly.Now that the case is deadlocked, I have to start over from the scene. I squatted beside the bed, letting the disgusting smell hit my olfactory nerves. The east end of the crib is where Fu Li is lying down.Under the position of the original head of the corpse, there was a large pool of blood, which had soaked into the mattress and spread around, forming a large pool of blood.The original lower body part of the corpse was stained with urine stains into a map shape, with yellow feces sticking to the center of the map. I leaned over to prevent the feces from rubbing against my body, and shone the bright flashlight on the bed sheet that was out of its original position. "There are some flakes of blood where the corpse is pressed, including the pool of blood on the head," I said. Lin Tao stood up, walked to me, and leaned over to look at the pool of blood: "I understand what you mean, if the corpse was lying prone or supine in this position in its original state, it is impossible for the blood to splash on the bed sheet here. " "But look, the bed sheet covered by Zhang Huarao's body doesn't have any blood splatters." I said, "The bed is so small, where and in what position was the dead man hit on the head?" The position of Zhang Huarao's body almost didn't need to be drawn in chalk to show the original condition. The sheets and walls around her head were covered with splattered blood, but the position of her head was a blank area. "I seem to have some ideas," I said, "but we need to make a comprehensive analysis based on the damage on the corpse and the distribution of bloodstains. After watching the scene in a while, I'm going to re-examine the corpse." Lin Tao raised his head to look at the ceiling and said, "Look, there is also a splatter of blood on the ceiling. But it seems that the splatter of blood is located a little farther back." "I'm going to look at the photos of the corpse again, and re-examine the damage of the corpse." I said, "You stay here and do a detection experiment. Use a hammer to dip some water to simulate the blowing action, combined with the blood spattering pattern at the scene , to see where the murderer was standing when he hit the head of the deceased, and how tall the murderer was." “好的，明天上午专案组会议上碰头。”林涛说。 我和大宝驱车重新回到程城市殡仪馆，把冰箱中已经冻成冰棍似的尸体拖了出来。 我在一旁打开笔记本电脑，用电脑上的照片比对眼前的这两具尸体。而大宝则穿上解剖服、戴上橡胶手套，准备对特征损伤部位进行局部解剖。 “尸体的原始照片就是这样。”我把笔记本电脑侧过来给大宝看，“男死者的面部是没有血迹的，说明他被打击枕部以后，就一直处于一种仰卧姿势，血迹都往下流了，没有流到面部。可是女死者的面部，甚至颈部、胸腹部居然也是没有血迹的。” “女死者头上没有开放性损伤，她没有出血，当然也没有血迹。”大宝说。 我切换到现场照片，说：“现场的床这么小，除了男死者躺着的位置，就只剩下女死者躺着的位置了。而且女死者的头部周围都有喷溅状血迹，为什么唯独女死者的面部、颈部、胸腹部没有被血迹喷溅到？” “呃……因为他们俩正在忙活？” “你是说，之所以女死者身上没有见到喷溅状血迹，是因为女死者被东西覆盖了。”我说。 “对啊，被男死者覆盖着呢。” “我开始怎么没有注意到这一点呢，女死者不可能盖着被子，因为即便盖着被子，头面部也应该有喷溅状血迹，如果头面部也蒙在被子里，那她头部周围床单则不应该有喷溅血迹。” “那个，这有什么问题呢？” 我没说话，放下电脑，戴上手套，切开了男、女死者额头部位的损伤。 “皮内出血，”我说，“这样的出血，通常是两个硬东西中间有软东西沉淀，硬东西相撞，在软东西上留下的痕迹。” 大宝点点头：“而且巧在两个人的额头头皮都有这样的皮内出血，形态一致。” “好吧，那我们现在就把现场重建一遍。”我说，“案发当时，付离和张花娆的位置是一上一下，付离在上，张花娆在下。凶手撬门入室后，用锤头从背后多次连续打击付离的后脑，导致付离当场死亡。这个时候，因为付离的头部下方有张花娆的头部沉淀，两个头颅会发生激烈碰撞，形成两人额头上的皮内出血。” 我顿了顿，接着说：“付离被打击后迅速死亡，凶手又把付离的尸体翻到一边。此时张花娆因为头部受撞击，处于半昏迷状态，凶手随即又用锤头打击张花娆头部，导致她随即也死亡。” “嗯，”大宝说，“这样一来，尸体上所有的损伤都能解释了，但是好像对案件侦破没有什么帮助吧？” “开始完全没有想到这么细，”我说，“既然重建了现场，那么问题就来了。” "what is the problem?" 第二天一早，我和大宝满怀信心地坐在专案组会议室里。旁边坐着的，是同样也满怀信心的林涛。 “经过我们昨天复勘现场和复检尸体，基本把凶手在现场的活动过程还原出来了。”我开门见山地说，“通过现场、尸体上的血迹分布和尸体上的一些特征性损伤，我可以断定，凶手行凶的时候，男女死者正在发生性行为，凶手是从背后突然袭击的。” “我赞同。”林涛说，“根据昨天的现场实验，依据喷溅血迹形态和天花板上的甩溅血迹形态，凶手确实是在女死者躺着的位置前侧发动攻击的。” 专案组的所有人脸上都是一副迷茫的表情。大家都在想，工作一天，就得出这么个结论？ 我接着说：“好，既然是正在发生性行为的时候被打击致死，那么请问，女死者体内的精液是哪里来的？” “大小便都失禁了，精液不可以失禁吗？”有侦查员问道。 “有的重度颅脑损伤案例中，确实有滑精的现象，”我说，“但是精液失禁和射精是不一样的，提取发现的位置和量的多少都有区别。” “这个也不应该算是个问题吧。”曹支队长转头对小杨说，“精液不是送去DNA检验了吗？结果怎么样？” 小杨支支吾吾半天，说：“DNA结果今天上午才能出来。” “今天上午？”曹支队长大发雷霆，“都几天了，DNA还没出来？” 小杨说：“最近DNA实验室接的打拐任务重，本来我们认为这个案子没有什么问题，查完因果关系就破案了，所以对精液的检验也不是很重视。” “可以理解，我们开始也都先入为主了。”我为小杨开脱，“之前我们确实都认为此案无须刑事技术的支持，矛盾关系明显，只需要深入调查就可以破案的。” 曹支队长说：“那我们下一步该怎么做呢？” 我说：“我们通过对现场以及现场的衣物进行勘查，发现凶手进入现场后，没有任何翻动现场的迹象，也就是说凶手并不是为了财。痕迹检验通过对撬门的痕迹进行分析后，确认撬门的工具是一把类似瓦工铲的工具。这样的工具不是杀人或者盗窃的利器，而应该是随身携带的物品。” 我喝了口水，接着说：“结合尸体的检验结果，死者确实是被锤类工具打击头部，而我们又在现场发现了一个就地取材的锤子的痕迹物证，这都说明，凶手作案完全是出于临时起意。” “我们之前就是这样分析的，”曹支队长说，“凶手可能是和张花娆有约的另一名男子，看到张花娆和别人正在发生性关系，一时气愤，杀了两人。” 小杨此时突然插嘴说：“DNA室刚刚来了消息，张花娆的阴道擦拭物检出一名男性DNA，不是付离的精液。” 专案组里开始有了一些小的嘈杂。 “果然不是付离的精液。”我说，“这个精液应该是犯罪分子的。” “这倒是个好消息，我们有了犯罪分子的指纹和DNA，离破案不远了。”曹支队长说。 “那我接着说，”我说，“如果凶手是为了泄愤，那么他进入现场后，对女人施加的打击力度应该大于男人。而我们检验发现，男人的损伤比女人的严重得多。这恰恰提示了凶手要致男人于死地，而并不想致女人于死地的一种心态，对女人头部的打击可能只是为了让女人失去反抗能力。” 曹支队长点了点头。 我接着说道：“凶手打死男人后，翻过男人的尸体，又对女人的颞部打击了几下，然后奸尸。女人全身没有发现任何抵抗伤、约束伤或者是泄愤损伤。如果凶手只是因为醋意大发而去杀人，那么他势必会在女人尸体上泄愤，制造一些多余的濒死期损伤或死后损伤。这说明这个凶手的主要目的还是性，而不是愤。” “我补充一点，”林涛插话道，“我们在门闩上发现了一枚血指纹，血经过检验是男死者的。这就说明，凶手在杀死付离和张花娆后，又去大门处摸了一下门闩。显然不是为了从大门处逃离，因为他的出入口很确定是在后门。那么，他为什么要去摸一下门闩呢？这个问题困惑我很久。昨天，我又在窗户的窗帘一角，发现了一些擦蹭状血迹，应该是凶手带血的手擦上去的。我才豁然开朗。” 林涛的这个发现让我很吃惊，惊得一时合不上嘴巴。 林涛接着说：“我觉得凶手杀完人到奸尸之间，有一个活动过程。活动的内容是检查大门的门闩是否插好，并且把窗帘拉上了。” “你是说凶手进入现场的时候，窗帘是没有拉闭的？”我问。 “是的，从擦蹭状血迹的方向看，那个动作应该是拉窗帘的动作。”林涛自信地说。 “你的这个发现太关键了！完全印证了我的想法。”我兴奋地说，“刚才我们说到，凶手侵入室内作案的主要目的是性，而不是情、仇、债，那么，是什么刺激到凶手，让他下杀手的呢？肯定也是和性有关。” 我低头整理了一下思路，说：“我大胆地推测一下，很可能是付离和张花娆在发生性关系的时候，被凶手看到了。凶手一时兴起，就用随身携带的瓦工铲弄开了后门。因为大门是铁门，而且是闭合状态的，所以凶手只有选择从后门进入。进门后，凶手没有过多的动作，杀完人，检查门窗状况，奸尸，然后走人。” 大宝点头道：“嗯，我完全同意。凶手之所以会不放心，去检查门闩，又在深更半夜不顾屋内温度高，拉闭窗帘，就是因为他害怕有别人和他一样，看见刺激的场景，就想干一些刺激的事情。” “是的，”我说，“这就说明了凶手的防卫戒备心理，这种心理是从他自己的犯罪手法里总结出来的。简单地说，他怕别人效仿他。” “分析得很在理。”曹支队长说，“那么，我们之前的侦查方向就完全错了，对于下一步工作的开展你们有没有什么好的建议？” 我点点头，说：“刚才说了，这个人随身携带瓦工铲，那么他很有可能就是一名瓦匠，而且必须是居住在附近，或者在附近工作的人。因为案发当晚十点钟左右，他必须有条件经过这个偏僻的现场，而且一定是偶然经过。” “瓦匠，现场附近？”侦查员皱着眉头说，“在现场附近工作的瓦匠是有几个人，因为这一带的房子还有一些人在请瓦匠帮忙装修。” “对，就从这些人入手，因为晚上十点通常是加班结束的时间。”我说。 “我还要补充一点，”林涛说，“现场北侧有一扇窗户，之前我们也分析了，凶手很有可能是在窗户这里窥视到了屋内的春光，然后绕到后门作案。这扇窗户的下方是一个花坛，昨天我们发现窗帘上的血迹以后，就对花坛仔细进行了勘查。” 我用期待的眼神看着林涛。 林涛看了我一眼，接着说：“花坛里有一些杂乱的足迹，但是有一处足迹踩踏了几根小草。根据小草倒伏的状态，我们判断这一处足迹是最新鲜的足迹。也就是说，这一处足迹很有可能是犯罪分子的足迹。” “有比对价值吗？”其实我这个问题意义不大，因为凶手的指纹和DNA我们都掌握了。“没有比对价值，”林涛意味深长地看了我一眼，说，“因为这处足迹只有一个足尖部分。” 我知道林涛看我的这一眼，是告诉我，这个足尖痕迹是有深意的。我想了想，豁然开朗，说：“你是说，凶手是踮着脚的。” “是的，据我们测量，窗口离地面的高度是一米五五，身高一米七的人站在窗口才可以勉强看到窗内的情况。”林涛说，“凶手极力踮起双脚往窗内窥探，说明他的身高应该在一米六左右。另外，根据我们现场实验，发现身高一米六左右的人在现场床前挥动铁锤，才可以在天花板的特定位置留下甩溅状血迹。” “身高一米六左右，男性，瓦工。”我总结道，“另外，付离枕部的损伤非常严重，颅骨大面积凹陷性骨折，脑组织崩出、四溅，这说明一个问题，这个人的力量非常大，应该是个很健壮的男人。” “可以了，”主办侦查员笑眯眯地说道，“有了这些指标，也就能锁定犯罪嫌疑人了。依我看，符合这样条件的人，在现场附近不会超过五个。” “而且有指纹，”曹支队长说，“五分钟就可以比对完毕。如果你们这次分析得没有错，下午就能破案了！” 我终于睡了一个甜美的午觉，没有做任何梦。 是林涛把我从深度睡眠中推醒的。 “案子破了，”他眉开眼笑地看着我，“喂，堂兄，去旁听审讯不？” 我们到达审讯监控室的时候，眼前那个其貌不扬的矮壮男人正在低头吸烟。 艺术源于生活，和电视上一样，一旦犯罪嫌疑人用颓废的声音说道：“能给根烟抽吗？”通常他就要交代罪行了。 “我……我就是，一……一时冲动。”这个矮壮男人抽完烟，果然结结巴巴地说了起来，“我……我讨不到……到老婆。我也……也想……” “不要说理由，直接交代那天晚上你做了些什么。” “我……我那天……那天晚上去给……给一家铺地……地砖。” 我是个急性子，实在受不了这么磨叽的询问。于是点了根烟，走到隔壁侦查员办公室里打开电脑开始玩空当接龙。 过了大约一个小时，林涛在背后拍了拍我的肩膀：“堂兄，别玩儿啦。咱们的分析完全对上了。” “哦，怎么交代的？” “那天晚上，他下工以后经过现场，”林涛娓娓道来，“结果被一阵女人的浪叫声吸引了，他循着声音一直找到了这间亮着灯又没有拉窗帘的房子，然后躲在窗口下，踮着脚看屋内。那可真是春光乍泄、一览无余啊。还巧了，他曾经在现场隔壁干过活，了解现场的房屋结构。于是他一时冲动，撬开了后门，进门就杀人，然后奸尸。” “其实挺简单的一个案子，”我说，“我们开始就是先入为主了，不然不会绕这么多弯路。” “是啊，”林涛点头，“先入为主害死人。” “不行，我们现在往回赶吧？”我笑着说，“明天就是铃铛的生日了。另外，你准备送给你铃铛姐什么礼物啊？” “到家都十点多了。”林涛说，“到哪儿去买礼物？不然我把你送她吧。” “靠，”我做出一副鄙视状，“我又不是你的。” 铃铛的生日宴会开得很成功，案件破获，心里没有了负担，大家都喝得很尽兴。 晚上，我躺在床上看着天花板，说：“对了，有件事儿忘记告诉你了。” 铃铛乐滋滋地扭过头来：“嗯，啥事儿？好事儿还是坏事儿？” “是件好事儿，”我微笑着说，“你妹妹笑笑的案件，终于有眉目了！”
